Composite material pretension screen for oil field shale shaker

There are many different kinds of replacement shaker screens according to different shapes of the screen frame and material. Below is the most normal type shaker screen type we normally used:
1)    Hook type (hard hook) replacement screen. It is mainly for below type of shaker models:
Derrick 513 and 514 shaker and mud cleaner, Derrick 2000 or 48-30 shale shaker or mud cleaner.
2)    Frame type replacement screens. The frame screen is mainly for GN brand shale shaker and mud cleaner, Mongoose type shale shaker and mud cleaners, Cobra, King Cobra series shale shaker and mud cleaner. VSM-300 series shale shakers.
3)    Soft hook screen. It is a very old type screen model. Fewer shakers utilize the screen type. As the soft hook screen cannot last long time. Its quality is not good. But as its lower price, may some old shaker type still use it.

Tell from the materials, there are 2 types of frame screen: steel frame and composite material replacement screen.
Compared with steel frame screen, composite material screen can lost for a longer time, and it can be stocked for a longer time. Normally, the steel frame screen can only stock 1 or 2 years. If it stocks a longer time, the screen quality can be reduced, as the steel material cannot last long time even with suitable warehouse protection. But the composite material can last a longer time. You can stock the composite material for 4 or 5 years, if you do not need to use them. The reason is as the special design of the composite material screen. Inside of the composite screen, it is steel frame for reinforce. And then a special kind of plastic material to cover and fill the steel frame. As its complex production, the composite material price is higher than steel frame, but it can last a longer time.
GN Solids Control is a professional manufacturer for different models and type replacement screens. Welcome you contact GN group for more information of replacement shaker screen model.

A full set 1500hp on shore oil rig mud system ready for shipment

This week, a full set of 1500hp on-shore oil and gas drilling rig mud system will be ready and dispatch to the clients.
It is a standard oil and gas drilling mud cleaning system composed of 4-stage solids control equipment as well as the degassers.
The full 1500hp mud cleaning system is composed of below items:

1500hp rig mud system

1)    1 ea mud gas separator (poor boy degasser) before the mud system. It is used to cut the intrusive gas in the mud before shale shaker.
2)    The 1500hp mud system is composed of 3 ea linear motion shale shaker for pre-separation. It is the first stage separation.
3)    After the 3 shale shakers, there is a vacuum degasser used to cut the fine gas bubble and protection the hydro cyclone separators. As the hydro cycone is a kind of pressure device. The gas bubble may make damage to the cones.
4)    A separate set desander mud cleaner and a desilter mud cleaner is followed after the degasser. They work for the second and third stage separation. After desilter separator, most particles above 27 microns will be removed.
5)    As the desander, desilter can only remove particles bigger than 27 microns.  The smaller size is out of its working range. After some circulation, the fine solids contents will be higher and higher. The drilling mud will be too weight for drilling activities. A big bowl decanter centrifuge model GNLW452 is equipped after desilter to recovery the valuable barite and reduce the mud weight.
6)    Over 30 sets mud agitator and mud guns are equipped with the mud system for better mixing and to avoid the mud settle down.
7)    Furthermore, the 1500hp mud system is with a jet mud mixing system to prepare new drilling mud.
The whole 1500hp mud cleaning system is divided into 3 parts – mud recycling tank, mud mixing and storage tank, water and fuel tank.
